white hole
Let an agent describe white holes as hypothetical objects, clearly marking their unconfirmed status and separating theory from speculation.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent describe white holes as hypothetical objects, clearly marking their unconfirmed status and separating theory from speculation.
A hypothetical region of spacetime that nothing can enter from outside but from which matter and light can escape, a time-reversed counterpart of a black hole allowed by solutions of general relativity; there is no confirmed observation.
What it is for: A concept in theoretical physics and cosmology.
It can be explain the theoretical idea; distinguish from black holes; summarise proposals and critiques; mark speculation clearly.
